Thats your opinion but having several undrafted RBs near the top of the rushing list for the last 5 season suggests otherwise. (Arian foster, jay ajayi, justin forsett, chris ivory, alfred morris) Then u add the others who have been just as effective Isaiah Crowell, cj anderson, lagarette blount, latavius murray, 6th round pick, etc. Other likes lamar miller and devonta freeman are 4th and 5th rounders. Not really sure how you are making that point. It is much easier to find value at RB later on draft day than DB which again makes me question how unless you're talking about AP u could possibly take a RB over a DB. There is one DB who went undrafted who can be considered a top player at their position. That's chris harris jr. Cant say the same for RB. Dallas also has one of the best o-lines in recent nfl memory. Their o line is what is punishing teams not their RBs. Demarco, McFadden and zeke are all 1K rushers behind that line.
